Special multipliers

• every 5th level = base x 2
• every 10th level = base x 3
• every 25th level = base x 5
• every 50th level = base x 10

base is the percentage that the level belongs to in the above range, e.g. 0.5% for level 50.
Only the highest applicable multiplier is considered for calculation, meaning level 150 will be 1% x 10 = 10%.
